Subject says it all really. This is on my new ASUS AT3IONT-I which is now up and running as it should be, apart from this problem of course. The media resides on an internal HDD in the core that uses the LMCE file structure and mounts to /mnt/device/##. The MD has nothing in /mnt, so the symlinks in the public video, audio etc folders are not working.

I will try my other MDs later to see if they have the same problem, but in the meantime, any thoughts?

I had this same error, but only with subtitles. It used to work fine with AVI files with subtitles, and now it doesn't work at all (and I get that error msg), so I delete the subtitles file to watch the movie.

I have recently made a second partition on this hard drive to hold backups (sdb2). So when I plugged the HDD back in (after installation), I said to use sdb1 with LMCE file structure (like I usually do), and said to ignore sdb2. Could the problem be ANYTHING to do with this?

Don't seem to have write access to sdb2 in KDE desktop if that is relevant (not that I need it). Also the sda1 volume is not present in "Places"; it always used to be.

The HDD is in /mnt/devices/ on the core/hybrid as it should be, and the symlinks are working as they should on the core/hybrid also.

To recap, I have an internal hard drive for media (sdb) which only used to have one partition (sdb1), using LMCE directory structure, public, always worked no problem. Then I made a small second partition (sdb2) for my clonezilla image backups, which I "ignored forever". This was when I got the problem.

I moved the images to an external HDD, reverted the internal sdb drive back to one partition, removed all traces of it from LMCE in web admin (thanks for the tip Joakim) and everything from unknown devices. Rebooted, LMCE detected it, and MDs could see it.

Don't think the problem was necessarily caused by what I have just described, but it happened none the less. I suspect it was a one-off installation issue, fairly sure the permissions were messed up somehow.
